Title: Electrode array
Inventor: EDOWAADO POORU SUMISU
IPC: G08C19/00
Filed: 1990-07-05
Abstract: PURPOSE: To minimize a difference between crossover capacitance and peak capacitance by changing the shape of an excitable electrode so as to fix a capacitance ratio when a meter needle is moved on the excitable electrode. CONSTITUTION: The area of the region A-3 of the excitable electrode 4-1 and the region A-4 are practically equalized. That is, the area of the region where the meter needles 9 and 10 face when the needles 9 and 10 cross the surface of the electrodes 4-1 to 4-10 is equal to the area of the opposite region when the needles 9 and 10 are moved on a certain electrode. For the electrodes of the electrode arrays 4-1 to 4-10, all points on an inner edge 83 closest to a center electrode 2 are not in an equal distance from the electrode 2. Then, the inner edge 83 is turned to a recessed shape and the needles 9 and 10 face the region of the practically equal area at all times while crossing a prescribed electrode surface.  Thus, for the capacitance ratio between the center electrode and the respective ten electrodes at respective needle positions, the difference between the crossover capacitance and the peak capacitance is made smaller.

Title: Thinfilm transistor and manufacture thereof
Inventor: SHINAGAWA TAKAAKI
IPC: H01L21/336
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To decrease the off-current of a thinfilm transistor, by providing an opening part at least at a part on a region in contact with an active layer in a semiconductor layer to grow to source/drain regions, etching the part of the semiconductor layer to grow to the source/drain regions thinner than the film thickness, and obtaining the thin film. SOLUTION: After a resist 6 is applied to polycrystalline silicon 5, the resist 6 is patterned in the island shape. At this time, an opening part 7 in the resist on the region in contact with an active layer is provided at the following process. The polycrystalline silicon 5 is etched by dry etching using etching gas CF4 and O2 . At the opening part 7, the etching rate becomes later by about 30% than the surrounding part of the island. When the etching is finished, a semiconductor layer becomes thin film to 5-10 nm excluding the overetching amount by the request for the process, and a remaining thinfilm region 8 is formed. The resistance of the opening part 7 is increased by the thinfilm formation. The OFF current of a thinfilm transistor can be decreased without increasing the manufacturing processes at all.

Title: Offsetting control circuit
Inventor: YONETANI HIROYUKI
IPC: H03F3/34
Filed: 1988-07-15
Abstract: PURPOSE:To automatically correct the offsetting of a comparator, a differential amplifier circuit and the like without using an external terminal in an LSI internal part by correcting the input level of a controlled circuit by the correcting level set automatically so as to make the offsetting of the controlled circuit into zero. CONSTITUTION:When an initializing signal Is is set to H level, the comparing input of a comparator 1 which is a controlled circuit and the reference input are mutually shorted to the same potential and a comparing output Co is switched to the detecting input side of an output change detecting circuit 3. When a resetting signal Rs is given, an output level I of a variable level generating circuit 4 is continuously changed and added to the reference input level of a comparator 1 by a level control circuit 5. When the input level passes through a point which becomes an offsetting zero, the output change detecting circuit 3 switches a detecting output Do from H level to L level simultaneously when the comparing output Co is changed and stops the stepping action of a counter 41. Thus, the input offset of the comparator 1 is automatically corrected.

Title: Ceramic insulation container for high-voltage vacuum discharge device
Inventor: AOKI SHINICHI
IPC: H01H33/66
Filed: 1987-07-15
Abstract: PURPOSE:To upgrade production yield of a vacuum switch tube by making a band- shaped protruding part of an inner wall formed in a ladder-type shape and next by forming a specific value or less of a ratio of thickness of the band-shaped protruding part of the inner wall to an average thickness of a ceramic container and by defining a prescribed range of an angle formed between the ladder type surface and the inner wall surface. CONSTITUTION:When an average thickness of an alumina ceramic container 1, a thickness of a ladder-type band-shaped protruding part of an inner wall, and an angle formed between the ladder-type surface and the inner wall surface are assumed to be (a), (b), and theta respectively, a ratio of thicknesses is made to be b/a>=1.2 and a relation composed between the ladder-type surface and the inner wall surface is made to be 30+50b/a<=theta<=50+50b/a. For example, if a=4.5mm, b=7.2mm, and b/a>=1.2 are assumed and when the angle theta formed between the ladder-type surface and the inner wall surface is made to be 30+50b/a<=theta<=50+b/a, a set value of theta=120 deg. can be obtained. A rubber press is used to perform pressing of a prescribed pressure, and an external surface of a ceramic cylinder is cut and next fired to form a vacuum switch tube. Hence, production yield of the vacuum switch tube can be upgraded.

Title: Method and device for manufacturing packing vessel
Inventor: YAN NIIGUREN
IPC: B65B31/04
Filed: 1983-09-26
Abstract: The manufacture of non-returnable packages for e.g. milk is frequently carried out by the conversion of web-shaped, laminated packing material to a tube, filling of the tube with milk, and sealing and forming to filled packing containers of the desired, e.g. parallelepipedic, shape. For the forming, which is done by means of external forming devices, the contents are made use of as a holder-up for the forming device pressed-on from the outside, so that the desired shape can be achieved without creasing or other deformations.The abovementioned forming principle works less well if the packing containers are not completely filled, but have a certain air space, so-called headspace. The proportioning of the contents also becomes uncertain and the desired accuracy of volume cannot always be achieved. These difficulties are overcome in that a sealed off part of the packing material tube is pressurized with the help of gas during the forming process, so that the internal back pressure required during the forming is obtained, independently of the quantity of contents. The method also permits an accurate proportioning of the contents either by continuous feed at a controlled flow rate or by discontinuous feeding in portions. The invention also relates to an arrangement for the realization of the method.
